BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 444,270, dated January 6, 1891. Application filed April 3, 1890. Serial No. 346,368. (No model.)

Lake Mills, in the county of J eiferson and State of Visconsin, have invented a new and useful Churn and Butter-\Vorker; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying dra\ ings, and to the letters of reference marked thereon, which form a part of this specification.

My improved device is especially adapted for use at creameries, where large quantities 'of cream are churned and large masses of butter are worked, and Where the mechanism is usually driven by steam-power.

The object of my invention is to provide a device in which cream may be churned and a mass of butter may be automatically worked, the butter being squeezed or pressed together, flattening it out, and turned and pressed in a transverse direction, carrying on this alternating process successively until the milk and water are entirely removed from the butter, the device being so constructed as not to crush the globules of which the butter is formed,

thereby preserving the consistency and qual-' ity of the butter.

In the drawings, Figure l is a side elevation of the complete device. Fig. 2 is a top plan view of the device, parts being broken away to show the interior construction, a second position of some parts and other removable parts being shown in dotted lines. Fig. 3 is a rear elevation of the device, parts being broken away to show interior construc-.

tion. Fig. 4 is a detail of supporting and operating mechanism. Fig. 5 is a top plan view of a modified form of the device, parts being in section to show interior parts.

A is the supporting-frame. The receptacle or drum B consists of the short hollow cylinder 0, having a complete rigid head D in one end and a rigid head D in the other end, which head D has a central aperture E, of considerable size, for the free introduction and removal of the material to be operated on to and from the drum for the introduction of operative mechanism into the drum. The drum is provided with a spindle or arbor F, affixed rigidly centrally to the head D, which arbor has its journal-bearings in the frame A. The drum is also provided with a spur toothed rim G, secured rigidly to the head D, being fastened directly to re-enforcing pieces H, which are placed against and affixed to the head D. The rim G meshes with a gear-wheel G, which meshes with a pinion 011 the driving-shaft I. The driving-shaft I has its journal-bearings in the frame, and is provided with fast and loose pulleys I and I for carrying a belt thereon running from the powersupplying mechanims. The drum is thus adapted to revolve, but at a comparatively low rate of speed. The cylinder is provided with a series of apertures J J, which are adapted as the cylinder rotates to discharge the milk or water from the drum into the semicircular trough J, from which it is discharged through an aperture at its lowest point.

Two swinging. arms K K, hinged on the fralne,are adapted to support the rollers and mechanism for working the butter, which when in use are within the drum B, but which may be swung out of and away from the drum, in the manner indicated in dotted lines in Fig. 2,for the convenience of the operator in putting the butter into the drum or removing it therefrom and for the purpose of washing the rollers and related mechanism. A roller L, provided with an arbor L, is supported revolubly by its arbor in elongated hearings on a post 011 the arm K, being arranged normally within the drum B at a little distance from and parallel to the cylinder 0 and preferably somewhat above the plane of the axis of the drum. A corrugated or longitudinally-ribbed roller M, having a rigid arborh is supported revolubly by its arbor in elongated bearings 011 a post on the arm K, which roller M is located normally near to and parallel withthe roller L, and so as to take therefrom the butter that passes over the roller L, carrying it forward to the other rollers, hereinafter to be described. Two other rollers N and N, lo-

cated normally in the drum and on the side opposite to the roller L, are arranged at right angles to the drum and to the roller L. These rollers N and N are provided with fixed axles, which have their journal-bearings in arms 0 and O, rigid in the swinging arm K. These rollers are arranged parallel to each ot her and at a little distance apart, the roller being adjustable through its hearings in the arms and 0 toward and from the roller X. The adjustment of the roller N on the arms 0 and t) is provided for in the construction shown in the drawings by having the journal-box on the arm 0 movable along the arm 0 and by providing two or more sockets in the arm 0 for receiving the axle of the roller therein. The axle of the roller N is provided with a pinion I", n'ieshing, when the mechanismis in the normal position shown in Fig. 2, with a pinion on the shaft 1, having its bearings in the arm K. The rollers Xand X are preferably arranged at a slightly-downward inclination toward their inner ends, as shown in Figs. 1 and A sprocket-chain. It, running on wheels on the shafts I and I and on the arbors L and M, rotates the rollers T M, and X when the shaft I is in motion.

It will be understood that when this device in use the mass of butter in the drum will, as the drum revolves in the direction shown by the arrow in Fig. 1, be carried up the side of the drum and will pass between the side of the drum and the roller L, whereby it will be pressed and flattened to a certain extent and will pass over the roller L onto the roller M, by which it will be carried forward and dropped down upon and between the rollers N and h", between which it will. pass, being thereby compressed in a transverse direction, and will then fall onto the cylinder at the bottom to be again carried up around and over the roller L, repeating the process until the milk and water shall be entirely removed from the butter, the milk and water in the meantime passing out through the apertures J into the trough J. \Yhen the butter has been sufficiently worked, the pin S, which socures the swinging ends of the arms 1i and K together when the butter-worker is in use, is removed, and the arms K and K are swung outwardly, carrying with them the rollers and related mechanism within the drum, so that the butter may be readily removed therefrom and the rollers can be conveniently cleansed. Asthe arm K is swung outwardly the sprocketehain R can, if preferred, be removed from its wheels. If found desirable, a half cover or apron Y may be put over the upper part of the aperture E, as shown and indicated by dotted lines in Fig.

In working small quantities of butter a modified form of my mechanism, such as I have shown in Fig. 5, may be used. The arbor F ofthc drum 13 may be provided with a crank-handle 'l for rotating it. The roller L may have its arbor supported in bearings fixed on the frame, and being unconnected to any mechanism for driving it is merely an idle pressure-roller. Butter being placed in the drum and it being rotated in the proper direction by the handle T, the butter will be carried up its side along between the drum and the roller L, whereby it will be pressed to a certain extentand will be carried over the roller and fall onto the bottom of the cylinder, to be again carried up between it and the rollers L, as before. This process may be continued until the butter shall be sufficiently worked.

To convert the device into a churn, the arms K and K are swung outwardly, thereby removing the rollers from the drum in the manner shown in dotted lines in Fig. 2. The apertures .l' .I are closed by stoppers W \V, (indicated in dotted lines in Fig. 8,) and a cover Y (indicated in dotted lines in Fig. 1) is placed over the aperture E and secured to the head D by the swinging buttons \V \V.

'l. he cream may when the quantity is small be placed in the drum before the cover Y is secured thereto; but the cover 1s preferably provided with an apperture therefor arranged to be closed by a stopper or small cover.
